Google owns Youtube (and gmail, most popular mail provider). You should think more deeply about what ads are and what are governments motivations. It is both the same thing. Google and META want power, they want money, because money is a voting power for allocation of resources in the society. Chinese governments want power, so they can have more money and more voting power for allocations of their resources.
The nationality of people in these governments doesn't matter at all to them. Chinese government doesn't care about regular Chinese citizens no more then US government does about their own. They simply care for their own power/money. And that is their interests.
Google and META work with the governments, they have actual NSA offices and follow any orders from the government, just like TikTok does. The problem here has nothing to do with what country it is in, it is simply that one set of rich folks are bothered that they can't control something other rich folks are controlling. People, in both cases, suffer and have no power whatsoever in the process.
I don't think you understand the point of view people critisizing Biden. Democrats are the ones that put Trump in power, just so they can have an easier elections and don't have to place more popular candidates to run against them. Voting for Biden is simply accepting defeat, that their plan worked and that they can do absolutely anything and you will support them because they will also support a worse candidate on the other side at the same time. It is not looking at the big picture, long term. In the future they can get someone like Trump to be a Democrat candidate and support someone even worse on the Republican side and you will have to vote for them under exactly the same situation. Democrats have a candidate that literarlly funds a genocide and we would think that once that line is crossed people would simply say that is enough, but apparently even Hitler would be elected in US elections as long as he places someone worse as prime candidate of another party.
